And whoever strives only strives for [the benefit of] himself. Indeed, Allah is free from need of the worlds.
The Saheeh International Quran Translation
وَمَن جَٰهَدَ فَإِنَّمَا يُجَٰهِدُ لِنَفْسِهِۦٓ إِنَّ ٱللَّهَ لَغَنِىٌّ عَنِ ٱلْعَٰلَمِينَAnd whoever strives only strives for [the benefit of] himself. Indeed, Allah is free from need of the worlds.
